Abstract
The utility model relates to a wall-attaching mechanism of a tower crane. An embedded steel structural component is arranged on a wall body of a building exceeding twelve stories. A movable anchor ear is installed on the headframe of the corresponding tower crane. The movable anchor ear adopts the structure that the movable anchor ear is provided with a cross arm and 2 to 8 connecting holes. A loop bar is covered outside the cross arm, holes are also arranged on the loop bar, and the holes are connected with the connecting holes at the different positions of the cross arm through a bolt. A pin hole is arranged at the left end of the cross arm, and is connected with a left arm rod through a wrist; a pin hole is arranged at the right end of the loop bar, and is connected with a right arm rod through a wrist. Pin holes are also respectively arranged at the other ends of the left arm rod and the right arm rod, and are connected with an inner arm rod through a wrist, and the connecting hole at one end of the inner arm rod adopts a long hole. Three holes which are not evenly distributed are arranged on the inner arm rod, and are respectively connected with the inner arm rod and the embedded steel structural component through three connecting rods. By applying the wall-attaching mechanism of the headframe of the tower crane of the utility model, even if the headframe of the tower crane is very high, the centre of gravity is increased, the danger that the headframe falls can be avoided.
Description
Affiliated technical field
The utility model relates to the attached wall mechanism of tower crane derrick.
Background technology
It is high-rise that modern building more and more tends to, and the matching used tower crane derrick of institute is also corresponding very high, because center of gravity increases, the danger that derrick is toppled over also strengthens.
The utility model content
The purpose of this utility model is the attached wall mechanism that the tower crane derrick is provided in order to address the above problem, even the tower crane derrick is very high, center of gravity increases, also the danger that can avoid derrick to topple over.
The technical scheme that its technical matters that solves the utility model adopts is: on the building masonry wall that surpasses 12 layers on floor, and pre-buried steel framing member.On corresponding tower crane derrick, movable anchor ear is installed.The structure of movable anchor ear is such, and a cross-arm has 2-8 connecting bore.Be with loop bar in cross-arm outside, on loop bar, also have the hole, be connected with the connecting bore of diverse location on bolt and the cross-arm.Left end at cross-arm has pin-and-hole, is connected with the left arm bar with bearing pin; Right-hand member at loop bar has pin-and-hole, is connected with the right arm bar with bearing pin.The other end at left arm bar and right arm bar also has pin-and-hole, is connected with interior armed lever with bearing pin, and the connecting bore of interior armed lever one end is a slotted hole.Three not uniform holes are arranged on interior armed lever, be connected with interior armed lever, pre-buried steel framing member respectively with three pipe links.For increasing the effect of holding tightly of movable anchor ear and tower crane derrick, be bonded with sheet rubber in the inboard of left arm bar and right arm bar.According to the height of building, movable anchor ear only can be installed 1-8.
Effective effect of the present utility model is, uses the attached wall mechanism of tower crane derrick of the present utility model, even the tower crane derrick is very high, center of gravity increases, also the danger that can avoid derrick to topple over.
Description of drawings
Figure is the structural representation of the attached wall mechanism of tower crane derrick of the present utility model.The pre-buried framing member of 1-among the figure, 2-pipe link, 3--bolt, 4--right arm bar, 5-sheet rubber, 6--bearing pin, 7-loop bar, 8--connecting bore, 9--bolt, 10--cross-arm, armed lever in the 11--left arm bar, 12--.
The specific embodiment
On the building masonry wall that surpasses 12 layers on floor, pre-buried framing member (1).Pre-buried framing member (1) is used steel material.On corresponding tower crane derrick, movable anchor ear is installed.The structure of movable anchor ear is such, and a cross-arm (10) has 2-8 connecting bore (8).The cross section of cross-arm (10) is 30 * 30 millimeters.Be with loop bar (7) in cross-arm (10) outside, also have the hole on loop bar (7), the connecting bore of going up diverse location with bolt (9) and cross-arm (10) is connected.Left end at cross-arm (10) has pin-and-hole, is connected with left arm bar (11) with bearing pin (6); Right-hand member at loop bar has pin-and-hole, is connected with right arm bar (4) with bearing pin (6).The other end at left arm bar (11) and right arm bar (4) also has pin-and-hole, is connected with interior armed lever (12) with bearing pin, and the connecting bore of interior armed lever (12) one ends is a slotted hole.Three not uniform holes are arranged on interior armed lever (12), be connected with bolt (3) with interior armed lever (12), pre-buried framing member (1) respectively with three pipe links (2).For increasing the effect of holding tightly of movable anchor ear and tower crane derrick, be bonded with sheet rubber (5) in the inboard of left arm bar and right arm bar.
Claims (3)
